Recently, the divergence within the US stock SaaS/cloud sector has been widening: MongoDB rose over four percentage points, with database demand under AI workloads being repriced; Snowflake edged up slightly, as the narrative around AI data platforms persists. On the cybersecurity front, Fortinet dipped a little over one percentage point; DigitalOcean fell over four percentage points, with its exposure to small and medium-sized cloud service customers drawing attention.

Newly listed stocks like WhiteFiber, which focuses on AI data centers + HPC GPU cloud, also fell over three percentage points in this wave, with its market cap just over $1B. Analysts have a strong buy rating for the next 12 months, but its small-cap status and high beta prevent it from avoiding profit-taking. Small-cap stocks like Keel Infrastructure also fell, following the market sentiment.

The overall difference lies in scale and maturity—leading blue-chip stocks like MongoDB/Snowflake are relatively stable in direction, while small-cap stocks like WhiteFiber/Keel/DigitalOcean experience amplified volatility. Currently, the demand for AI data infrastructure is real, but how to add leverage depends on the company's size and cash flow.
